We used to have a female Budgie that would only bathe in Lemonade.
R-Whites Lemonade to be exact and no other brand.
We'd tried other brands but she'd take a sip, realise it wasn't R-Whites and go and nip someone for putting the wrong stuff in her "bath" saucer.
If she sipped it and it was R Whites lemonade, she would then proceed to "break dance" in it in a frenzy of excitement for 5 minutes, until completely covered, and then go and sit on my father's shoulder to dry off.
Also, apart from the lemonade obsession, she liked Kellog's Frosties serial. Anyone watching TV whilst eating Frosties would suddenly find an aggressive Budgie in the bowl claiming the contents for herself.
We just happened to have a dominant female Budgie for a pet, who'd already broken the spring on two cages so that she was never shut in. She also decided that she didn't like being covered up at night, so come the time, she'd climb up on top of her cage and lock her claws in defiance. The cover cloth would be placed over the cage and warnigs given, but their she'd sit in protest. We'd place the cloth over her head and shoulders like a shaw and tease her about it, but she would still not give in. The look of, "Oh you are sooooo going to pay for this!!" was always very strong on her face. In the end she won and her cage was never ever covered up in the end.
And then their was the time next door's mentally retarded Irish Red Setter wandered into the house and living room, looking for its oqner and the Budgie attacked it.
My uncle, who was outside on the drive fixing his boat, saw the dog come out of the house looking distressed with the birds tail stuck out of its nouth. The dog came up to him for help and their was the Budgie "Bobby" with her beak firmly clamped around the dog's tonque so hard it was drawing blood.
My uncle made the bird let go and then the bird started to bite and attack my uncle. My father had a laugh about it and said, quote, "Of course she's pissed with you.... she was winning.....she had the dog by the throat!!"
And when we took her to the vet because she'd lost 50% of her feathers in the fight, she decided that she didn't like the vet and started to attack him.
We used to have a sticker on the cage stating "Warning, killer Budgie!!"
She was the type of pet a Klingon Warrior would have.
That was all way back in the late 1980's and she died in 1991.
